What the heck are you talking about!!?? Have you seen the DS lately? Have you read Nintendo Power Magazine lately(probably not)! There's Children of Mana, Final Fantasy III, Final Fantasy IV, Final Fantasy V, Final Fantasy VI, Final Fantasy Crystal Chronicles: Ring of Fates, Magical Starsign, Summon Night: Swordcraft Story, Summon Night: Swordcraft Story 2, Yggdra Union, Contact, Maroio and Luigi: Partners in Time, Dragon Quest Heores: Rocket Slime, Lunar Knights, Tales of Phantasia, Age of Empires: Age of Kings, and Pokemon Mystery Dungeon, and Ranger.
And there's a lot more too, so don't tell me there aren't enough RPGs.
